High Specification Thermal Backer Boards Are Vital For Underfloor Heating How Run Your New Electric Underfloor Heating Economically.

The latest electric underfloor heating systems are capable of providing safe and economic heating. However there is a lot of confusion regarding claims by some suppliers of heating mats who maintain that theirs is an ultra efficient cost saving version. The fact remains that 1kw of electricity will produce 1 x kw of heating. Therefore, a floor area of say 20 square meters using 130w heating mat will produce 2.6kw of heating The secret of getting economical heating is to begin with a high specification insulation layer. The underfloor heat up time is determined by the thermal conductivity of the sub-floor that it is fitted on It is therefore vital that a thermal backing board is fitted over the sub- floor before the heating mat is fitted. This should have a thermal conductivity of 0.027(W/mk) and a U value of below 3.5 (W/mK) This thermal conductivity is a calculation of the rate at which a material will pass heat energy. This is measured in watts per square meters per degree of temperature difference (watts meters) per degree of temperature A good insulating underlay will force the heat upwards instead of letting it disperse back down through the sub-floor, meaning that far more of the heat that the matting is generating is in turn heating the room. This will in turn mean that the heating thermostat can be turned down by the corresponding degrees, thereby saving power and electricity costs. It is also important to remember that high thermal conductivity below the heat matting helps to give a fast warm up time of the floor surface -less than 20 minutes can be achieved. Thickness of the insulating backer board has a direct bearing on the thermal resistance. A thicker board having a greater thermal resistance than a thinner one, so if final floor thickness is not an issue, then go for a thicker board every time. You will also find that there is hardly any price difference between the board thick nesses. This is because the face material of the board and the manufacturing labour is the same regardless of board thickness.

When choosing an insulating backer board, compressive strength kPa is very important. Look for a board with a high rating over 300 kPa as this will ensure strength sufficient to support the weight of the heat mat, adhesive, floor tiles and any heavy appliances or furniture that will be resting on the floor. 300kPa is nearly equivalent to 30 tones per square meter. The facing of the board should be a consideration. A fiberglass scrim on either side of the board, coated with a polymer will assist in adhesion of the tile adhesive as well as providing greater structural stability. This also means that the boards can effectively be used to level up old uneven floorboards. This can be an alternative to covering the floorboards with expensive plywood which has little thermal resistance. However if the sub-floor is flexing, a plywood layer may be the only option. The boards can be cut and installed extremely quickly.

They can usually be cut with a Kraft knife and are either screwed into a wood floor, or bonded onto a solid substrate with a fast setting flexible tile adhesive. To summarize. 1. Do not lay your heating without a thermal backing board- it will waste electricity and money in the long run. 2. Buy waterproof boards that have at least 0.027 W mk thermal conductivity and a compressive strength of over 300kPa. 3. Buy boards that are mesh backed on both sides- these are slightly more expensive than un-backed boards, but will perform better.

One of the most searched for items on the Internet recently has been "scientists hail frozen smoke." I was intrigued by the article in The Times that started this frenzy and decided to investigate further as I was researching super insulating materials.

According to The Times "frozen smoke" is, "one of the world’s lightest solids, can withstand a direct blast of 1kg of dynamite and protect against heat from a blowtorch at more than 1,300C."

The company that make the product, Aerogel, do so by extracting water from a silica and then replace it with gas such as carbon dioxide. This creates an extremely light material 99% of which is made up of gas contained in millions of nanopores and although it is classed as a solid the gas gives it a semi-transparent appearance. Aspen Aerogel are creating an insulated lining for space suits. They believe that a 18mm layer of aerogel will be sufficient to protect astronauts from temperatures as low as -130C. But getting the stuff into a conservatory at the moment is going to be a bit expensive, although prices will drop in the next few years. Some people have experimented with aerogel insulation and reported big savings in their heating bills. Where space it at a premium, a thin layer of aerogel will outperform traditional insulation blankets. But it is its potential as a replacement for glass that we are most interested in. A Swedish company are experimenting with producing aerogel glass. This will provide low U-values with the equivalent thermal insulating quality equal to five to ten double glazed units. Unfortunately, at the moment experimental production is currently limited to just 15 square meters a month.

Other benefits of Aerogel Glazing when it does become available will be that; inert gases will not leak from between double or triple glazed units;

the glazing at just 12mm thick will be lighter than multiple-glazed units; it will provide better sound insulation; and since no low-e coating will be required, better light transmission. All this should mean that conservatory blinds and awnings will become a thing of the past, ventilation will be less critical and living with a south-facing conservatory will also be less of a problem. So we look forward to installing aerogel in a conservatory in a few years.
